Description

Technical Field

[0001] This utility model relates to the field of electrical equipment testing technology, specifically a rapid diagnostic device for multi-circuit harness testing. Background Technology

[0002] In modern electrical systems, multi-circuit wire harnesses are widely used in many fields such as automobiles, aerospace, and communication equipment. Their performance directly affects the safe and stable operation of the entire system. Therefore, it is crucial to accurately test parameters such as the conductivity, insulation, and contact resistance of the wire harness. However, existing multi-loop wire harness inspection devices generally suffer from low inspection efficiency and cumbersome operation. Traditional inspection equipment often requires manual connection and inspection of each wire harness, which is time-consuming and labor-intensive, making it difficult to meet the rapid inspection needs of large-scale production. Furthermore, due to significant differences in wire harness specifications and models across different application scenarios, existing devices have poor adaptability to wire harness specifications and cannot flexibly handle diverse inspection tasks. In addition, some inspection devices lack structural stability, making them susceptible to deviations in inspection results due to external interference, and the single method of wire harness fixing makes it difficult to guarantee the accuracy and consistency of wire harness position during inspection. Therefore, we propose a rapid diagnostic device for multi-loop wire harness inspection to solve these problems. Utility Model Content

[0004] The technical solution of this utility model is: a rapid diagnostic device for multi-loop route harness detection, including a workbench, a computer fixedly connected to the upper surface of the workbench, a printer fixedly connected to the upper surface of the workbench, the printer being electrically connected to the computer via wires, and multiple sets of parallel fixed plates fixedly connected to the surface of the workbench, each fixed plate having a first sliding groove on its side wall, each fixed plate having a limiting hole on its surface, a limiting rod slidably connected to the inner wall of the limiting hole, and a first sliding plate slidably connected to the inner wall of the first sliding groove.

[0005] Preferably, the surface of the first sliding plate is provided with a plurality of parallel strip-shaped through grooves, and the inner wall of each of the plurality of strip-shaped through grooves is provided with two symmetrically arranged second sliding grooves. The inner wall of each of the plurality of strip-shaped through grooves is provided with a circular hole, and the inner wall of the circular hole is fixedly connected to a first return spring. The other end of the first return spring is fixedly connected to a second sliding plate, and the lower surface of the second sliding plate is fixedly connected to a trapezoidal block.

[0006] Preferably, multiple parallel junction boxes are fixedly connected between the multiple sets of fixing plates, and each of the multiple junction boxes has a wiring hole on its side wall.

[0007] Preferably, each of the multiple junction boxes has an internal cavity, and each of the multiple junction boxes has a round rod on its upper surface. The lower end of the round rod penetrates the surface of the junction box and extends into the interior of the wiring hole. A circular piece is slidably connected to the inner wall of the cavity, and the circular piece is fixedly connected to the surface of the round rod.

[0008] Preferably, a second return spring is fixedly connected to the lower end of the circular piece, and the other end of the second return spring is fixedly connected to the inner wall of the cavity.

Simultaneously, multiple parallel fixing plates, a sliding first sliding plate, and a cleverly designed junction box allow for the simultaneous fixing and testing of multiple wire harnesses.

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0015] This invention provides an improved rapid diagnostic device for multi-loop route bundle detection. The technical solution of this invention is as follows: like Figure 1 - Figure 7 As shown, a rapid diagnostic device for multi-loop routing detection includes a workbench 1, a computer 2 fixedly connected to the upper surface of the workbench 1, a printer 3 fixedly connected to the upper surface of the workbench 1, the printer 3 being electrically connected to the computer 2 via wires, and multiple sets of parallel fixed plates 4 fixedly connected to the surface of the workbench 1. Each fixed plate 4 has a first sliding groove 5 on its side wall, and each fixed plate 4 has a limiting hole 6 on its surface. A limiting rod 7 is slidably connected to the inner wall of the limiting hole 6, and a first sliding plate 8 is slidably connected to the inner wall of the first sliding groove 5.

[0016] Furthermore, the surface of the first sliding plate 8 is provided with a plurality of parallel strip-shaped through grooves 9. The inner wall of each of the plurality of strip-shaped through grooves 9 is provided with two symmetrically arranged second sliding grooves 10. The inner wall of each of the plurality of strip-shaped through grooves 9 is provided with a round hole 11. A first return spring 12 is fixedly connected to the inner wall of the round hole 11. The other end of the first return spring 12 is fixedly connected to a second sliding plate 13. A trapezoidal block 14 is fixedly connected to the lower surface of the second sliding plate 13. By operating the second sliding plate 13, the position of the trapezoidal block 14 can be flexibly controlled to adjust the fixing components of different specifications of wire harnesses, thereby improving the adaptability of the device to wire harness specifications.

[0017] Furthermore, multiple parallel junction boxes 15 are fixedly connected between the multiple sets of fixing plates 4, and wiring holes 16 are opened on the side walls of the multiple junction boxes 15.

[0018] Furthermore, each of the multiple junction boxes 15 has an internal cavity 17, and each of the multiple junction boxes 15 has a round rod 18 on its upper surface. The lower end of the round rod 18 passes through the surface of the junction box 15 and extends into the interior of the wiring hole 16. A circular piece 19 is slidably connected to the inner wall of the cavity 17, and the circular piece 19 is fixedly connected to the surface of the round rod 18. Through the design of the junction box 15 and the wiring hole 16, a standardized interface is provided for the wire harness connection testing equipment, which facilitates the orderly access of the wire harness to the testing system, while protecting the internal wiring connection and preventing external interference.

[0019] Furthermore, a second reset spring 20 is fixedly connected to the lower end of the circular piece 19. The other end of the second reset spring 20 is fixedly connected to the inner wall of the cavity 17. The second reset spring 20 provides reset power for the circular piece 19 and the round rod 18. When no external force is applied, it can automatically reset the extrusion piece 21, ensuring the consistency and stability of each wire harness fixing operation.

[0020] Furthermore, each of the multiple junction boxes 15 has two symmetrically arranged compression plates 21 inside. The upper compression plate 21 is fixedly connected to the lower end of the round rod 18, and the lower compression plate 21 is fixedly connected to the inner bottom surface of the wiring hole 16. The two compression plates 21 are arranged vertically, which can apply compression force to the wire harness from different directions to achieve a firm fixation of the wire harness. Moreover, the upper compression plate 21 can move with the round rod 18 to adapt to wire harnesses of different thicknesses, thereby enhancing the fixing effect and versatility.

[0021] Working principle: By pushing the second sliding plate 13 outward, the trapezoidal block 14 is displaced. At the same time, the trapezoidal block 14 releases its contact with the round rod 18. Under the action of the second return spring 20, the upper squeezing plate 21 is displaced upward. At this time, the wire harness to be tested is placed between the two squeezing plates 21. Then, the second sliding plate 13 is released. Under the action of the first return spring 12, the trapezoidal block 14 is displaced backward so that it contacts the round rod 18, thereby fixing wire harnesses of different specifications. When the tested wire harness needs to be removed, simply pull the two squeezing plates 21 of the second sliding plate 13 to squeeze the wire harness. When all the wire harnesses on the equipment need to be removed, simply remove the limit rod 7 and then remove the first sliding plate 8 to remove the wire harnesses.

[0022] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
